Abstract

A fifth-order turbine-governor and a third-order oil-firing boiler model for a steam power plant are developed and combined into a complete plant model. A classical PID controller and an Optimal Integral Controller are applied to the plant model, and the results are compared for two different load levels and different kinds of disturbances. Special attention is given to the turbine throttle pressure behaviour and to the overshoot in firing intensity following the disturbances. The suitability of Optimal Integral Controller has been demonstrated. The final model and control system can be used for dynamic stability studies of large interconnected systems.
